    摘要: The present invention provides a top-emission-type organic EL display device, that is, an organic EL display device which can suppress changes of a threshold voltage and a light emitting start voltage, and the generation of brightness irregularities. The organic EL display device includes lower electrodes arranged on a main surface of an element substrate, a multi-layered organic EL layer arranged on the lower electrodes, and a light transmitting upper electrode arranged on the organic EL layer. A layer in contact with the lower electrode of the organic EL layer forms a hole injection layer constituted of a V2O5 layer.
